T 0 all whom it may-concern:

Be it known that I, HERMANN KRUSKOPF, a citizen of the German Republic, and resident of Dortmund, Germany, have invented certain new and useful Improvements in Methods of and Mean for Extinguishing or suffocating Explosions in Mines, of which the following is a-specification.

This invention includes the provisions of improved means forsuspending dust containing receptacles in the drifts of a mine in such a manner that the rush or shock of air preceding an explosion will cause the receptacle to be moved from its support to scatter the dust and permit the same to be blown by the air for extinguishing or suffocating thefollowing flames.

This invention has for its object to provide an improved hanging device for such receptacles or containers comprising a plurality of arms, carrying at one end the tilting receptacles or containers, and the opposite ends of which resting freely on or engaging suitably the tops of the timber-work or other specially provided supports, so that the suspended receptacle will be securely held in position. Under the action of shocks, the receptacle may be swung and immediately tilted or it causes one arm or a set of arms to be disengaged from the supporting bracket, whereby the receptacle will be allowed to drop, The impulse of the swinging movement is produced by the shock of air if an explosion occurs, said shock striking the front of the receptacle. My im proved hanging device provides for a perfect breaking of the receptacles containing the extinguishing medium, without reducing the area of cross section of the drift, as well as for the convenient release of such receptacles, even if the devices are not perfectly attended to. The easy and ready mounting and removal of the device is especially advantageous in the progress of the drift timbering.

In the accompanying drawings I have illustrated three forms of embodiments of the part of my invention by way of example.

The hanger arms 0 are firmly or pivotally -by means of pins dconnected to each other or to the tilting receptacle g, the up per ends of said arms resting on or suitably engaging the tops 6 supported on the posts a of the timber work. As shown in Fig. 1,

l the tilting receptacle 9 is provided with a 1920. Serial H0. 394,597.

= lower cross pin f, freely supported in the angle formed between. the arms 0, said receptacle being held in place by means of ribbons it which may be easily torn.

According to Fig. 2, the a'rms c are pivotally connected to each other through the agency of an intermediate member 2', upon which the tilting receptacle is supported by means of two pins 7 secured to said receptacle. In the embodiment shown in Fig. 3 the arms 0 are pivotally connected to the receptacle g.

The shock of air preceding the flame of explosion, for instance from the right to the left, strikes against the right hand wall 9 of the receptacle and has a tendency to shift the receptacle towards the left, whereby the ribbons It will be'torn away and thence};- tacle tilted. The gripping end 6 of the right hand arm 0 may also be disengaged from the top 5 to enable the receptacle to drop upon the floor, scattering its contents, across the section of the drift.

In the embodiments shown in Figs. 1 and 2, a double possibility of tilting is provided, as in these instances the receptacles may be tilted by the shock of explosion without cooperation of the sup-porting arms.

Having now fully described my said invention, what I claim and desire to secure by Letters Patent, is: I

1. A fire extinguisher, comprising pairs of arms, a connecting element adapted to pivot one end of each pair together, the free ends of the arms having hanger extension adapted to rest on supporting means, a member carried by the arms, and a receptacle for fire extinguishing material balanced on said member.

2. A fire extinguisher, comprising connected arms arranged substantially at right angles and having the free ends bent out wardly and supported on beams, and a receptacle for fire extinguishing dust tiltably supported at the connected portion of the 100 arms.

3. A fire extinguisher, comprising pairs of arms connected in pivotal relation with each other at one end portion, normally disposed in angular relation with each other and hav- 105 c. Supporting means for a non-combustible dust container, comprising arms pivotally connected together at one end, and means for normally balancing and supporting the dust container adjacent the pivots, the opposite ends of said arms adapted to rest on portions of the drift of a mine, whereby the force of an explosion in the drift will unbalance the container to scatter the dust therein.

5. Supporting means for fire extinguishing dust containers, comprising collapsibly connected arms having means on which said containers are supported, said arms adapted to rest on'portions of the drift of a mine,

whereby the force of an explosion in the drift of the minewill cause the arms to collapse and upset the containers.

6. Supporting means for fire extinguishing dust containers, comprising relatively movable arms arranged at one-end to carry a dust container and having the other ends loosely engaging suitable supports, whereby the force of an explosion will cause a moveterial, of a hanger therefore movably con resulting from an adjacent explosion'or like air disturbance.

9. The combination with a receptacle.

adapted to oontaiirfire extinguishing material, of a hanger including pairs oi relatively movable arms movably'connected to the receptacle and adapted to rest on a support and removable therefrom, the connection between the arms and receptacle permitting a movement of the receptacle result ing from an adjacent explosion or like disturbance for relatively moving the arms to remove them from the support.

10. The combination with a receptacle adapted to contain fire extinguishing material, of pairs of arms having one end of each pair movably mounted with respect to the receptacle and adapted to carry it, and having the other ends adapted to rest on suitable supports, whereby the concussion from an adjacent explosion or like disturbance will cause a movement of the receptacle and the arms will move from the supports.

In testimony whereof I have hereunto set my hand in presence of two witnesses.

HERMANN KRUSKOPF.
